Development of $$beta$$$$^{+}$$-$$gamma$$ based AMOC measurement system

Konishi, Suzuka*; Ueda, Daisuke*; Xu, Q.*; Hirade, Tetsuya  ; Tsuchida, Hidetsugu*

In order to elucidate the transient damage state by ion beam etc., positron annihilation lifetime - momentum correlation (Age-MOmentum Correlation: AMOC) apparatus by $$beta$$$$^{+}$$-$$gamma$$ simultaneous measurement is newly constructed by the digital method. In this study, we investigated the effect of $$gamma$$-irradiation of polystyrene using the AMOC apparatus. As a result, we obtained that the S parameter near 1 ns decreases corresponding to the increase of damage amount.
